When the real Harry Potter dies, James and Lily perform a dark ritual that summons an infant to them. The infant that is summoned just so happened to be the only child of the Royal High Elves, the King and Queen Padreon and Evain Proussalidi. The Potters had no idea that the child they had just kidnapped was the Elven princess, Harrienne Evangelia Proussalidi. They spelled her (glamours, potions, etc.) to look identical to their lost son – the real Harry Potter.

When Harrienne was five, and under the roof of the Dursleys, her parents (whom she knows nothing about at the time) were killed in a Elf-Werewolf dispute in Greece. At around the same time, she started coming into her Elven magic – she was able to cast proficient glamours and many wandless magics – though she was unable to perform any offensive or defensive magic. The only kind of magic she was able to do was mostly stuff like glamours, unlocking spell, the locking spell, levitation, silencing spell, muffling spell and cleaning spells.

The glamours that the Potters placed on her fell on her sixth birthday, but thanks to her advanced wandless magic ability (Elven magic) she was able to replace them without the Dursleys finding out.

At the age of 11, Harrienne – as Harry Potter – entered Hogwarts and tried everything to stay in the ‘BWL’ role. She did what she thought was expected of her, being the ‘BWL’ and all. At the end of 5th year, in the Department of Mysteries, she defeats Voldemort for good.

After killing Voldemort, Harrienne thinks that it might be safe to come clean with everyone about who she really was (she found out about her heritage and parentage during the summer of 3rd year, when she stayed in Diagon Alley that summer – she had gone to Gringotts). However, before she could make up her mind, Dumbledore once again sends her back to the Dursleys. At the Dursleys, she is beaten and starved for near on two weeks straight, until Vernon gets promoted at the drill company. The Dursleys and Harry are sent to Seattle, Washington in the USA.

Harrienne stays with them two more weeks, being abused and hidden, before she decides to leave. She leaves the Dursleys house, immediately dropping her glamours (most of them – not the glamours that hide her pointed elf ears). The petite, immortal beauty runs from Seattle, using her Elven senses to guide her through the thick forest.

She is halfway between Port Angeles and Forks, when she is attacked by two nomad vampires – Travis and Kali. The two, sensing a difference in Harrienne (they could tell she wasn’t human) and feeling threatened, they attack her. Harrienne is not as strong as vampires are, or as fast, but she is still powerful magically and her magic gives her the speed, strength and grace needed to fight back. However, she is no match against two newborn vampires, and is quickly overpowered. They don’t kill her, but Travis does bite her. They think that the bite would either kill her or turn her, so they leave.

The bite instead, mixes with her Elven magic, creating a hybrid Elf-Vampire.

She was several hours into her Turning (Mixing?) when back in Forks, Alice Cullen gets a vision and immediately sends Emmett and Rosalie out to get Harrienne and bring her back to the Cullen house.
